As an AI language model, I am not capable of personal preferences or opinions on subjective matters like "best photo". Beauty and value are in the eye of the beholder, and what may be considered the "best photo" by one person might not be the same for another. However, some iconic photographs that are widely regarded as masterpieces of photography include "Afghan Girl" by Steve McCurry, "Migrant Mother" by Dorothea Lange, "The Kiss" by Alfred Eisenstaedt, "V-J Day in Times Square" by Alfred Eisenstaedt, and "Moonrise, Hernandez, New Mexico" by Ansel Adams.
